German scientists dug 50 meters underground and discovered small
pieces of copper. After studying these pieces for a long time,
Germany announced that the ancient Germans had a nationwide
telephone network.

down, they found small pieces of glass, and they soon announced that
the ancient Brits already had a nationwide fibre optic network.

Israeli scientists were outraged. They dug 50, 100 and 200 meters
underground, but found absolutely nothing...
